Description: A coronary stent is a tube placed in the coronary arteries that supply the heart, to keep the arteries open in the treatment of coronary heart disease. It is used in a procedure called percutaneous coronary intervention (PCI). Stents reduce chest pain, but they have not been shown to improve survival, except in acute myocardial infarction.
Similar stents and procedures are used in non-coronary vessels e.g. in the legs in peripheral artery disease.
